Statistical Methods For Assessing Treatment Effects On Ordinal Outcomes And Selecting Optimal Treatment On Survival Outcomes Using Observational Data., Huirong Hu Aug 2023

Statistical Methods For Assessing Treatment Effects On Ordinal Outcomes And Selecting Optimal Treatment On Survival Outcomes Using Observational Data., Huirong Hu

Electronic Theses and Dissertations

This dissertation consists of two projects investigating statistical methods in causal inference and personalized medication using observational data. In the first project, we propose a parametric marginal structural ordinal logistic regression model (MS-OLRM) to assess treatment effects on ordinal outcomes. Average treatment effect (ATE) is used to measure the difference of the mean outcomes if all patients would have been treated compared with the outcomes if they would not have been treated. Many statistical methods have been developed to estimate ATE when the outcome is continuous or binary. The methodology on assessing treatment effect for an ordinal outcome is less …

Electronic Theses and Dissertations

Laser powder bed fusion (L-PBF) process represents a form of metal additive manufacturing (AM) where micron-level powdered material is selectively melted and fused layer by layer to create intricate three-dimensional parts. This process involves rapid melting and solidification, leading to intense thermocapillary convection within the molten pool. The melt pool is a crucial element of the L-PBF process and refers to the localized region where the powder particles are melted and solidified to form each layer of the printed part. The shape and dimensions of the melt pool directly influence the accuracy and surface finish of the printed part. Precise …


Using Graphic Novels To Teach Economics Content To High School Students With Extensive Support Needs., Caroline Mae Fitchett Aug 2023

Using Graphic Novels To Teach Economics Content To High School Students With Extensive Support Needs., Caroline Mae Fitchett

Electronic Theses and Dissertations

The purpose of social studies instruction in school is to facilitate the growth of competent citizens (National Council for the Social Studies [NCSS], 2013). Despite the recognized benefit of social studies instruction, emphasis on this subject has decreased over time, and has ultimately been termed a “dispensable subject” (Fitchett & Haefner, 2010). Social studies is an even more marginalized subject area for students with disabilities (Zakas et al., 2013). Expanding the research in this area is not only necessary to improving social studies academic content acquisition but is also likely to facilitate greater independence for students post-school – and by …


Perception Is Reality! How Perception Shapes Our World., Nicole Clay Aug 2023

Perception Is Reality! How Perception Shapes Our World., Nicole Clay

Electronic Theses and Dissertations

This thesis is an examination of the role different photography techniques play in how images are perceived. There have existed techniques for manipulating the perception of images since the creation of the camera. The techniques examined in this paper are editing, staging, and the use of captions. In recent years, perception has become a powerful tool for political parties to manipulate. This manipulation of perception has led to an increasing distrust in the images the media presents to the public. This paper does not seek to answer any questions but to encourage people to have a greater understanding of photography.


The Role Of E-Liquid Constituents In E-Cigarette-Induced Cardiac Arrhythmia And Autonomic Imbalance., Cory Kucera Aug 2023

The Role Of E-Liquid Constituents In E-Cigarette-Induced Cardiac Arrhythmia And Autonomic Imbalance., Cory Kucera

Electronic Theses and Dissertations

Introduction. Accumulating evidence indicates that exposure to electronic cigarettes (e-cigs) promotes sympathetic dominance and electrophysiologic instability in the heart, potentially culminating in arrhythmogenesis. E-liquids contain various formulations of nicotine and flavorings, but the effects of specific e-liquid constituents and their concentrations on e-cig-induced autonomic imbalance and electrical dysfunction are unresolved. To that end, we tested the hypothesis that e-cigs modify cardiac autonomic balance and ventricular arrhythmogenesis in mice dependent on e-liquid constituent type and concentration. Methods. Using a crossover design and a serial exposure regimen, ECG-telemetered male C57BL/6J mice underwent whole-body exposure to e-cig aerosols generated from e-liquids containing different …

Understanding Associations Between Chronic Illness Identity, Psychological Flexibility, And Type 2 Diabetes Emotional, Behavioral, And Psychosocial Functioning., Valery Bodziony Aug 2023

Understanding Associations Between Chronic Illness Identity, Psychological Flexibility, And Type 2 Diabetes Emotional, Behavioral, And Psychosocial Functioning., Valery Bodziony

Electronic Theses and Dissertations

Introduction: Illness identity, defined as the extent to which one integrates their illness into their sense of self, may be a key psychological factor to consider in overall adjustment to and management of Type 2 Diabetes. Emerging research suggests illness identity integration is associated with aspects of diabetes-specific functioning. Psychological flexibility has also been found to be associated with positive diabetes-specific functioning. This modifiable cognitive factor may play a role in the relationship between illness identity and diabetes-specific functioning. This study aims to examine associations between illness identity enrichment, illness identity rejection, psychological flexibility, and aspects of diabetes-functioning, including self-management …


Institutional Racism, Racial Trauma, And Mental Health In Bipoc Graduate Students And Professionals., Jody Zhong Aug 2023

Institutional Racism, Racial Trauma, And Mental Health In Bipoc Graduate Students And Professionals., Jody Zhong

Electronic Theses and Dissertations

While there is increasing mainstream focus on diversity, equity, and inclusion (DEI) amongst U.S. college campuses, institutional racism and everyday racist events continue to be common experiences for Black/Brown, Indigenous, and People of Color (BIPOC) students (Bartz, 2019; Noltemeyer et al., 2012; Pieterse et al., 2010; Regis, 2016; Vaishnav, 2020). Research has shown that subtle, everyday racist slights, known as microaggressions, can have a substantial effect on the mental health and functioning of BIPOC, leading to the development of posttraumatic stress and to negative impacts on psychological well-being (Abdullah et al., 2021; Le et al., 2021; Lui & Quezada, 2019; …


“Long Live Ear X-Tacy!”: An Oral History Study Of Rhetorics Of Nostalgia And Place., Aubrie Warner Aug 2023

“Long Live Ear X-Tacy!”: An Oral History Study Of Rhetorics Of Nostalgia And Place., Aubrie Warner

Electronic Theses and Dissertations

This study aims to explore rhetorical placemaking through how people understand and construct narratives around places that no longer exist. In doing so, it examines the relationship between nostalgia and place — how rhetorical construction of place is influenced and/or informed by rhetorics of nostalgia, how our experiences influence our sense of place (past and present), and how we create continuity for ourselves in the construction and maintenance of particular narratives. This study contributes to the emerging field of rhetorics of nostalgia and places it in direct conversation with rhetorics of place and unpacks how these two are more connected …


False Memories Are Impacted By Semantic Pairing Of Drm Lists., Ryan Coleman Aug 2023

False Memories Are Impacted By Semantic Pairing Of Drm Lists., Ryan Coleman

Electronic Theses and Dissertations

In the DRM paradigm, experience of semantically related words leads to false memories of related words called critical lures. These false memories serve as evidence that the relationship between items in a DRM list contribute to an overall gist or central concept for the experience. The present studies aim to investigate whether the higher-order semantic relationship that exists between different DRM lists can also influence recognition memory. Study 1 compared memory confidence ratings for list items and critical lures to two metrics: “Temporal Contiguity”, how closely in time lists appeared to each other at encoding, and “Semantic Distance”, the semantic …


Why Are Measures Of Depression Imperfectly Correlated? An Empirical Investigation., Eric Joseph Smith Aug 2023

Why Are Measures Of Depression Imperfectly Correlated? An Empirical Investigation., Eric Joseph Smith

Electronic Theses and Dissertations

Depression remains one of the most prevalent and impactful mental health disorders worldwide. A large number of measures of depressive symptoms are currently available, all designed to assess the same underlying construct. However, the measures tend not to correlate highly with one another. Measurement error cannot fully account for this observation, suggesting that clinical heterogeneity – that is, differences in symptom coverage across measures – might contribute to the lower-than-expected correlation between measures. We conducted two concurrent studies to examine this hypothesis. In Study 1, we developed a coding scheme to categorize items into one of 10 symptom categories. We …

Development And Applications Of Novel And Practical Fluorination Reagents., Yuhao Yang

Electronic Theses and Dissertations

The fluorine (F) atom has distinctive properties such as the highest electronegativity, small size, low polarizability, and strong C–F bond strength. Not surprisingly, fluorinated organic compounds have garnered significant attention in the pharmaceutical, agrochemical, and material fields. Since organofluorides are very rare in nature, we need fluorination reagents to help us transfer fluorine into the organic molecules. In past decades, a vast number of fluorination reagents have been developed and many of them are commercially available now. However, there is still much room for the improvement of these reagents. Our target is to develop novel and practical fluorination reagents to …

The experiments in Chapter Two investigated the role of the upper esophagus in airway protection through systematic activation of pharyngeal and esophageal mechanoreceptors in a cat electromyography model. Chapter Three compared effects of opioid administration on breathing and swallowing between male and female rats, and found that females are more susceptible to opioid-induced depression of breathing and swallow than males. Findings from Chapters Two and Three led to the development of a translational model of opioid-induced dysphagia using …


Inhibition Of Ras As A Novel Therapeutic Approach In Luminal B Breast Cancer., Raphael Ngozichi Jigo Aug 2023

Inhibition Of Ras As A Novel Therapeutic Approach In Luminal B Breast Cancer., Raphael Ngozichi Jigo

Electronic Theses and Dissertations

Historically, the RAS oncoprotein has not been implicated in breast cancer due to less than 1% of breast cancer cases bearing oncogenic RAS mutations. Recently, however, it has been reported that greater than 60% of Luminal B breast cancer cases have a decreased expression of negative RAS regulators RASAL2 and DAB2IP. Thus, in many Luminal B breast cancers, RAS remains in a constitutively active state without mutation, in turn driving oncogenesis. To date, there are no FDA-approved direct inhibitors of wild type RAS. We have developed a direct RAS inhibitor that acts on wild type RAS using in silico drug …


New Species Of Dryolestoid From The Late Cretaceous Allen Formation And Implications For South American Faunal Diversity., Brigid Erin Connelly Aug 2023

New Species Of Dryolestoid From The Late Cretaceous Allen Formation And Implications For South American Faunal Diversity., Brigid Erin Connelly

Electronic Theses and Dissertations

Dryolestoids are extinct cladotherians mammals from the Jurassic and Cretaceous periods. I describe a collection of dryolestoid specimens from the Late Cretaceous localities of Cerro Tortuga (Allen Formation), Anfiteatro 1, and Shining (both La Colonia Formation) from Patagonia, Argentina. Using comparative morphology, I identify a new species of meridiolestidan dryolestoid based on eleven specimens across both formations. The new species’ recovery from La Colonia Formation represents the first dryolestoid connection between the two approximately contemporaneous formations. The species’ morphology may represent an ecological shift within Meridiolestida from insectivory to herbivory, showing a transition in characters between the plesiomorphic sharp-toothed meridiolestidans …


Epitranscriptomic Regulation In Breast Cancer And Pcb-Induced Liver Disease., Belinda Petri Aug 2023

Epitranscriptomic Regulation In Breast Cancer And Pcb-Induced Liver Disease., Belinda Petri

Electronic Theses and Dissertations

Post-transcriptional RNA modifications including N6-methyladenosine (m6A) regulate mRNA stability, splicing, and translation. My research examined m6A in two disease models: breast cancer (BCa) and non-alcoholic fatty liver disease (NAFLD). Acquired resistance to endocrine therapies (ET) develops in approximately 20% of BCa patients with estrogen receptor α positive (ER+) tumors following treatment. The mechanisms by which tumor cells evade ET are not completely understood. Using a cell line model, we investigated the role of an m6A reader protein, HNRNPA2B1 (A2B1) that is upregulated in ET-resistant ER+ BCa cells. Stable overexpression of A2B1 in ET-sensitive MCF-7 cells (MCF-7-A2B1), results in ET resistance, …

Non-Western Rendition Of Ambient Rhetoric Of Khajuraho Monuments., Shiva Hari Mainaly Aug 2023

Non-Western Rendition Of Ambient Rhetoric Of Khajuraho Monuments., Shiva Hari Mainaly

Electronic Theses and Dissertations

This dissertation develops an ambient rhetoric: a living practice that is more disclosive than communicative, more entangled than intersectional, and more subtle than explicit and evidential. Rather than exploring the symbology, iconography, texture, and artistic integrity of Khajuraho monuments, I claim that Khajuraho monuments aim at convincing visitors with their persuadability and affectability inherent in their material bases, architectural panels, fractal design, allegorical cast, aura of attunement, and the environment in which the monument complex is nestled. Khajuraho groups of monuments in Central India, matchless in their monumentality, dynamic in their adjustment to the shifting socio-politico-cultural landscape in the world, …
